Description

Technical Field

[0001] The present invention relates to the technical field of signal acquisition, and in particular to a signal acquisition device and method based on remote education. Background Art

[0002] Distance education is a form of education that uses a variety of media to systematically carry out education and teaching, with the basic feature of quasi-separation between teachers and students. The distance education system not only provides academic education, but also non-academic education. It is an important means to expand the scale of education and popularize national education, and has become an important part of the lifelong education system. The information dissemination methods used in distance education include: correspondence through printed teaching materials, audio-recorded teaching materials, television-recorded teaching materials and other teaching materials mailed, wired broadcasting and wireless broadcasting, satellite television, and network transmission. In most cases, a system often adopts multiple methods to carry out distance education activities at the same time, and distance education often uses signal acquisition devices for learning.

[0003] When conducting physical education, because physical education requires a certain amount of running space, and students often need to use specific force techniques when running in curves, but due to the limitations of distance education, teachers are often unable to synchronously follow the rotating students to collect signals of the force status, which will affect the educational efficiency of distance education to a certain extent.

[0004] Therefore, when using the above-mentioned signal acquisition device, because students are often in a state of circular running, the signal acquisition device can often only observe the running students at a wide angle, which may lead to a certain degree of misjudgment of the students' force state, thereby affecting the students' learning efficiency.

[0018] A signal acquisition method of a signal acquisition device based on distance education, using the above-mentioned signal acquisition device based on distance education, comprises the following steps:

[0019] S1: By installing the Velcro belt loop on the student's waist and pulling the connecting rope to move to the appropriate position, the teaching video is displayed on the display screen. The student can run in a circle around the support assembly and the millimeter wave camera can be used to shoot the running student;

[0020] S2: When shooting with a millimeter wave camera, it is first necessary to scan the student's position through the area scanning module, and identify the human body through the human body recognition module. When the recognition is successful, the audio is collected by the audio acquisition module to form audio information. At the same time, the audio information and the feedback information generated by the human body recognition module are transmitted to the data processing module, and processed by the data processing module to form learning information. Finally, it is transmitted to the wireless transmission module to be transmitted to the teacher terminal through the wireless transmission module.

[0021] Beneficial effects of the present invention:

[0022] 1. On the basis of the conventional signal acquisition device, the signal acquisition method is improved, the Velcro belt loop is used to connect the connecting rope to the student's waist, and the student is driven to run in a circle around the support assembly, so as to collect the student's force state through the collection unit sliding on the connecting rope, so as to ensure that the collection unit moves synchronously with the student to realize the full monitoring of the student's force state, and at the same time, by controlling the collection unit to move on the connecting rope, the camera area can be enlarged and reduced, thereby greatly improving the collection accuracy of the entire signal acquisition device;

[0023] 2. During the use of the device, students will run in a circle around the support assembly. During the running process, it is inevitable to ensure that the circumferential radius of each running will be at a rated value, which will cause the connecting rope to be pulled during the running process. Under the action of centrifugal force, the entire device will often be deflected. When the pulling phenomenon occurs, the infrared tension meter on the device will monitor the change in tension, and drive several counterweight blocks to move through the weight adjustment assembly, so as to improve the anti-deflection performance of the entire signal acquisition device by connecting several counterweight blocks to the fixed magnetic block and increasing the tension on the fixed sleeve, so as to prevent the signal acquisition device from being deflected.

[0024] 3. When students are running, they will not only tilt outward but also tilt inward. When they tilt inward, the middle section of the connecting rope may collapse, causing the collection component to fall, which makes it difficult for the collection unit on the collection component to collect learning information. The present device can disconnect the electromagnet seat so that the card post can be inserted into the card joint, and drive the rotating seat to rotate through the first motor, so that the fixed sleeve can be reversed by the rotating rotating seat, so that part of the connecting rope can be retracted onto the fixed sleeve, thereby ensuring that the connecting rope between the support assembly and the student can always remain taut, thereby improving the ease of use of the entire signal collection device to a certain extent.

[0058] It should be noted that the method of using the above-mentioned signal acquisition and dispensing device includes the following steps:

[0059] S1: by installing the Velcro belt loop 307 on the student's waist and pulling the connecting rope 305 to move to a suitable position, the teaching video is displayed through the display screen 703, and the student can run in a circle around the support assembly 1, and the millimeter wave camera 2204 can be used to shoot the running student;

[0060] S2: During the shooting process by the millimeter wave camera 2204, the area scanning module 2201 is first used to scan the position of the student, and the human body is identified by the human body recognition module 2202. When the identification is successful, the audio is collected by the audio acquisition module 2203 to form audio information. At the same time, the audio information and the feedback information generated by the human body recognition module 2202 are transmitted to the data processing module 2205, and processed by the data processing module 2205 to form learning information. Finally, it is transmitted to the wireless transmission module 2302, so as to be transmitted to the teacher terminal through the wireless transmission module 2302.

[0061] The whole process can be achieved by installing the Velcro belt loop 307 on the student's waist and photographing the student through the collection unit 22 arranged on the connecting rope 305 to realize photographing the student's force posture, thereby realizing the collection of the student's learning information. At the same time, the weight adjustment component 9 can also be set to push a number of counterweight blocks 406 to move, thereby increasing the pressure on the recovery component 3, thereby alleviating the tension generated when the student pulls the connecting rope 305 when running in a circle to a certain extent. Finally, the tension state on the connecting rope 305 can also be judged by the infrared tension meter 706. When the tension is lower than the rated value, the electromagnet seat 506 is disconnected to insert the clamping column 501 into the clamping joint 304, and then the rotating seat 301 is driven to rotate by the first motor 606, and the fixed sleeve 303 is driven to reverse by the rotating seat 301 to realize the winding of the connecting rope 305, thereby ensuring to a certain extent that the connecting rope 305 between the recovery component 3 and the student can always be in a tensioned state, thereby preventing the collection component 8 from falling.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
